We all know a picky eater （挑食者） or two, or maybe you're the picky eater, avoiding food adventures at all costs, because you're convinced you'll hate whatever new and bad-looking food is put on your plate. But why is it that some people are picky eaters while others are willing to try pretty much anything that can be eaten？
There's no single explanation for the picky eating habit. Picky eaters are typically unwilling to try new foods, which can be the result of your DNA and the way you are treated and educated when you are young. Marcia Pelchat, Ph.D.， a researcher at the Monell Chemical Senses Center in Philadelphia who specializes in food preferences in humans, tells China Daily, "A group in Finland looked at what we call food neophobia, which literally means 'fear of the new'， and they found that there is some genetic basis for this."
"Also, if you have parents who don't really like to try anything new, you will also be exposed to fewer new foods," Pelchat says. The opposite is also true： Those who try new foods and have positive experiences are then more likely to try unfamiliar foods in the future.
People who are less adventurous may be more hesitant to try new foods. Trying anything new, food included, requires you to step outside of your comfort zone. If you're not very adventurous, you may have a tough time with this. People who seek new adventures or thrills might be more likely to experiment with food. "There is a thrill-seeking personality trait," Pelchat says. "It's been shown,especially with spicy food,that there is some connection between trying new foods and thrill seeking," she explains.
Most adult picky eaters start as child picky eaters. "It's normal for children to go through a picky stage when they're toddlers, maybe two or three years old, and that makes sense evolutionarily," Pelchat says. But as we get older, if we continue to avoid new foods, pickiness can persist.
